SX-EW Plant:

A percolation leaching leaching method has been widely used for coarser ore and has been blasting out of the ore body. Acid leaching agent is usually sprayed from the top of the seam, the solution of acid and acid soluble copperore reacts copper sulfate leaching out through the seam. Percolation leaching include heap leaching, dump leaching and tank leaching. 
(A) heap leaching. Including waste heap leach ore and ore heap leaching, the former is used to handleconventional low copper mining law abandoned ore, often open-air job, clustered rock piles (millions of tons), oreheap leaching agent from the surface sprinkle cloth; latter is the surface oxide ore heap fragmentation and polymineralization, generally up to 10 to 500 000 t of scale, mine ore mine waste heap than the slightly smaller heap leaching. 

(2) Dump leaching. Crushed ore with explosives first place, do not move the ore from the ore leaching agentspraying the surface. This method is used to process low-grade copper deposits in surface or underground copper deposit. It must be noted in the subsurface crack the case before the hydraulic pressure leaching. Whether it is in situ leaching or heap leaching, are required to have no leakage substrate (natural or artificial), in order to collectthe leachate. 
(3) Tank Leaching. In giant trough (e.g. length 25m, width 15m, depth 6m, the processing capacity of 3000 ~ 5000t ore), and sulfuric acid containing 50 ~ 100g / L was immersed crushed ore (less than 1cm). 

After the first few leachate purification sent by electrowinning copperproduction, the subsequent leaching solution used to leach the next batch of fresh ore. Compared with heap leaching and in situ leaching, tank leaching solution of sulfuric acid leaching using darker and have a higherproduction efficiency. 
Agitation leaching of finely ground copper-containing material with a leaching agent added together and stirred with a stirrer tank leaching, the particle size is less than 95% of the material was 75 / μm, leach solution containing sulfuric acid 50 ~ 100g / L. 

In addition to some of the oxidation of sulfide copper calcine and calcined after using agitation leaching beyond the general ammonia leaching and agitation leaching oxide leaching are used.
